Mask for processing convex hemisphere of gyro motor and processing method thereof

Abstract

The invention provides a mask for machining a convex hemisphere of a gyro motor and a machining method of the mask, and solves the problem that the performance of the gyro motor is influenced due to the fact that the machining precision of the convex hemisphere cannot be guaranteed by an existing machining tool of the convex hemisphere. The mask for processing the convex hemisphere of the gyro motor comprises a mounting sleeve, a hemisphere shell and an extension sleeve, the mounting sleeve, the hemispherical shell and the extension sleeve are sequentially and coaxially arranged, and a plurality of logarithmic curve spiral holes matched with the logarithmic curve spiral grooves of the convex hemisphere in shape are formed in the hemispherical shell in the circumferential direction; the invention provides a processing method of a mask for processing a convex hemisphere of a gyro motor. The processing method comprises the following steps: step 1, primary processing; secondly, a positioning mandrel and a positioning clamp are machined; step 3, processing an outer spherical surface; fourthly, the logarithmic curve spiral hole is machined through numerical control milling; fifthly, burrs on the outer spherical surface are removed; step 6, separating the mask workpiece from the positioning mandrel; and seventhly, burrs on the inner spherical surface are removed.
